Well what i know is that:
1 game = 1.6% energy spent (streaming / solo queue / team ranked / league)
1 training= 0.8% energy spent
Basically the energy that a player restore per day, you have to calculate yourself because it depends on facilities.
Just see how much you spend and calculate how much you player loses per day, the difference will be the restore % ;)
All facilities at 9 for example, restore 33.8%.
Hope it helps!
